"The Return of Cooler" actually does boast a truly awesome premise, but instead of fleshing out what could've been an engaging story, it rushes to the fight scenes. The action itself is acceptable, but the movie constantly beat me over the head with its wasted ideas, souring the experience.
Yet "Cooler's Revenge" works better upon second viewing because it isn't accompanied by the deadweight hype. On its own merits, it's briskly paced and excelled in the action department, so I was thoroughly entertained.
"Dragonball Z: The Tree of Might" seems like it wants to be more epic than your usual serial film, yet the characters are wasted and the story ends abruptly...yet it's also more epic than its predecessors and I was consistently entertained- despite its 'too long, yet not long enough' runningtime.
